this is an axial view of the shoulder.  
 
1. glenoid  
2. coracoid process  
3. acromion process  
2 is anterior to 3, ie the upper part of the film as displayed is anterior.  
 
it demonstrates the os acromiale, an unfused acromial apophysis.  
the acromial apophysis is a secondary ossification centre which  
normally fuses aged 18 to 20 years. this appearance is a normal  
variant which is often mistaken for a fracture on the axial view.  
it is usually bilateral.
